Degradation of the herbicide imazapyr by Fenton reactions
Tóm tắt
The degradation of the herbicide imazapyr has been carried out by three advanced oxidation processes involving iron ions as catalysts: Fenton’s reagent, photo-Fenton and electro-Fenton. We show that all processes are rapid and efficient. The kinetic rate constant was found to be
k=5.4×109 M−1
s−1. The mineralization of imazapyr is almost complete using the photo-Fenton and electro-Fenton processes.
